The mouth ofthe furnace,is closed by a refractory door I2 ha ving in it a hole 13 tobe engaged and an opening I through which elevation of my novel castingthe upper by a suitable tool for sliding the' United States my 1935,Serial No. 45,859 (Cl. 2257-1) oi; of March 3, 1883, as 1928; 370 O.

by means 01' a handle 36.

At the end of track 1, remote from furnace 9 there is mounted a butlerspring 31in a suitable the fusion of the material in cavity 30 and forbringing it'to the desired casting temperature,

- vigorous movement to carriage 2:3 away from the furnace. The movementof carriage 23 is quickly decelerated by contact of the pad 4i withspring- 31 and due to the inertia of the molten material in cavity 30 itis thrown through passage 3i and gate Tl into the casting cavity 26where, by its impact against the walls of the casting cavity, it isprojected into all parts of the said cavity. The mold 2.5 is prepared inany desired manner and may be at any requisite temperature forsuccessful casting. It is obvious that the track 1 may be somewhatinclined downwardly away from furnace 9 or the casting cavity 26 may bedisposed lower than the gate 21 to utilize gravitational force to retainthe molten material in the casting cavity until solidiflcation hasoccurred.

This invention may be manufactured and used by or for the Government ofthe United States of America for governmental purposes without thepayment of any royalties thereon or therefor.

What is claimed is:

1. In a device of the class described, a substantially horizontal track,a stationary melting furnace mounted thereon adjacent one end thereof,said furnace having an apertured' closure facing the other end of saidtrack, a carriage slidably mounted on said track, a mold on saidcarriage, a crucible mounted on said carrlage, said crucible having aportion adapted to extend through the aperture sure into the furnace,there being a cavity in said portion to contain material to be meltedand I posed to be compressed by said portion is in the a passage leadingfrom said cavity to the face of the crucible adjacent the mold inalignment with the gate in said mold, two rods secured to the lower sideof said carriage at the opposite longitudinal sides thereof, springsmounted under said furnace to be compressed by said rods when saidportion is in the furnace, a latch to retain said portion in the furnaceagainst the effort of said springs when compressed, and resilient buffermeans on said track to arrest the movement imparted to said carriage bysaid springs when said latch is withdrawn, whereby the molten metal insaid crucible is thrown through said passage and said gate into the moldby the force of momentum.

2. In a device of the class described, a track,

a carriage slidable thereon, a mold mounted on said carriage, anelongated crucible mounted on said carriage with one'end adjacent tosaid mold, said crucible having in it adjacent its other end a cavity tocontain material to be melted anda passage leading from said cavity tothe said one end of the crucible aligned with the gate in said mold,rods fixed to the lower side of said carriage a' stationary furnaceadapted to receive the portinof; the crucible having in it said ity 'tollmelfth material therein, springs {disrods whensaid furnace, a latch toretain said portion in the furnace against the effort of said springs,and a resilient buffer mounted on said track to arrest the movementimparted to said carriage by said springs when said latch is re? leased,whereby the molten material in said crusprings secured to in saidfurnace clocible is thrown through the said passage into said mold bythe force of momentum.

3. In a device of the class described, a track, a carriage slidablethereon, a mold mounted on said carriage, said mold having in it acasting cavity and a laterally extending gate opening thereinto, acrucible mounted on said carriage adjacent saidmold, said cruciblehaving a portion to extend into a melting furnace with a cavity thereinto contain material to be melted and a passage above the upper surfaceof the metal in said crucible leading from said cavity to that face ofthe crucible adjacent the mold and in alignment with said gate, means toimpart vigorous movement to said carriage, and resilient butler means toarrest said carriage to throw molten metal from the cavity in saidcrucible into the said casting cavity by the force of momentum.

4. In a device of carriage slidable thereon, a mold having in it acasting cavity and a container for molten metal mounted on said carriageadjacent each other, there being in said mold a laterally extending gateand in said container a laterally extending passage in alignment withsaid gate and opening adjacent the opening of said gate, rods secured tosaid carriage to extend parallel to said track, said track to becompressible by said rods, l'atch means to hold said carriage inposition against the effort of said springswhen compressed by said rods,and resilient buffer means to arrest the movement imparted to saidcarriage upon release of said latch means whereby the molten metal insaid container is thrown through said passage and said gate into saidcasting cavity by the force of momentum.

5. In a device of-the class described, a stationary furnace, a carriagemounted to slide toward and away from said furnace in alignmenttherewith, a crucible mounted on said carriage having a portion toextend into said furnace, a mold mounted on' said carriage adjacent saidcrucible, there being in said mold and crucible passages in alignmentwith and adjacent to each other, the said passage in the crucible beingabove the upper surface of the metal in said crucible, momentarilyacting means to propel said carriage away from said furnace, and meansto arrest the movement imparted to said carriage by said propellingmeans, whereby molten material in said crucible is thrown from saidcrucible through said passages into said mold by the force of momentum.

6. In a device of the class described, a mold and a container forliquefied normally solid material mounted adjacent each other for linearmovement as a unit, there being in said mold and said container passagesextending toward each other unit whereby the metal in said container ismoved upwardly and laterally and is thrown from said container throughsaid passages into said mold by the force of momentum.
